I enjoy tribute a lot, but if I was playing to win I'd be depressed as hell. I don't know what my win rate is but it's waaayyyyyy less than 50/50, and even assuming straight wins the time investment of three games is already 40-60 minutes at least.
I'm obviously just not that good yet, but this is after I've been playing steadily for three months and I haven't found many resources outside the game to help improve. So if the answer is just to play until it clicks, an incentive for casual participation would be a benefit.
The legendary victor's purse could still be rewarded for 3 wins from the activity finder page.
I know I'm just yodeling into the void but w/e.
Enjoy your games!
